Sell hfj compact spinning accessorial equipment @China (Mainland)

H-fang compact spinning accessorial equipment is four-roller device desigened for modification on traditional ring spinning.

HFJ compact spinning is four-roller device designed for modification on existing traditional ring frames. Enjoying perfect structure, good workship, its performance is well accepted ever since its launching market.

When modifying old ring frame, no need to drill on the beam frame, no need to chang anything on the driving parts or parts beneath the beam frame, thus will not destroy any part of the machine. For the drafting section, only change roller stand, front bottom roller, flute pipe unit and add compact device. Then change fan case and change roving creel. In case of top duct solution, even no need to change roving creel.

Basic Requirements for getting good result from compact spinning

1.Install traveling clearner.

2.Control temperature, humidity and dust content of the air in the workshop:

   A.Temperature:25-30℃constant in all year long

   B. Relative humidity:  55%±5% for cotton

                                   75%±5% for worsted

   C. Dust content of the air: <3mg/m3

Structure Features

1. Four-roller system, apron lattics are of positive drive.

2.  Negative pressure system adopt main blower with general air duct and filter net to avoild dirtying workshop.

3.  Modular design,6 spindles or 8 spindles in one unit.

4. Well-designed negative pressure distribution ensures consistency of airflow at each suction nozzle.

5.  The optimization designed suction nozzle on profiled tube, good for fiber compact.

6.  Inverter control for both energy-saving and pressure adjusting for different yarn count spinning demands.

7.  Smoothly moving of the yarn is guaranteed by tension device of the apron lattice (patent product of H-FANG).

8. Closed-loop control on negative pressure guarantee stable pressure during spinning.(For option)

9.  Auto-cotton striping device available for option.(For option)

Benefits from HFJ compact spinning

1. For cotton yarn, over 60% 3mm hairiness can be reduced.

2. Under the same process and working condition, the tenacity of compact spun yarn is 5%-15% higher than ring spun yarn.

3. Decrease CV%, increase fibre availability.

4.  Higher productivity when producing same tenacity yarn than conventional spun yarn.

5. Yarn twist can be reduced by 5-10% while maintaining same yarn strength.

6. Better evenness of diameter and hairness.

7. 30% reduction in yarn breakage in warping process.

8. Better abrasion resistance of yarn leading to fewer breaks in weaving.

9. Singeing can be omitted in case of compact siro-spinning.

10. Reduction of pilling and better dye uptake in fabric.

11. Increase productivity, especially for high density fabrics produced in air jet looms.

12. More clear in fabric texture for yarn dyed fabric, especially for warp-striped fabric.

13. Maintain tenacity which lost during noiron finishing.

14. More smooth and soft in fabric.  

15. Improve working conditions,reduce flyings in workshop.
